Abstract The nutritive and calorific values of seeds make them good sources of edible oils and fats diet. Many physical and chemical properties of fats and oils have been investigated. The experimental study evaluated the physical and chemical properties were analyzed on oil extracted from the cotton and Okra seeds and compared with those reported by the other researchers. Methodology: Cotton seed and Okra seed were pulverized using and electric blender and thereafter stored in polythen bag in a refrigerator. The oil was extracted from the resulting powder by entailed using soxhlet apparatus to extract with petroleum spirit of boiling point between 40-60 o C. 200g of the ground Cotton seed and Okra seeds were packed in muslin cloth and inserted into the soxhlet extractor and petroleum spirit was used as the extracting solvent for a period of eight hours. The extracted oil samples were evaluated for physical and chemical properties. The result were represented as means and standard deviations. Result The Okra and cotton seeds have percentage oil contents of 20.43±0.90% and 22.37±0.38%, density of 8.6±0.1 and 8.30±0.1, moisture content of 85.6±1.0 and 84.00±1.0 and specific gravity of 0.84±0.05 and 0.96±0.02 g/cm3 respectively. The chemical analysis carried out on the oil of okra and cotton seeds have the following properties: acid value of 0.5±0.1 and 0.45±0.02 mg KOH/g, saponification value of 162.7±0.50 and 185.00±1.0 mg KOH/g, iodine value of 5.94±0.1 and 5.64±0.05, peroxide value of 12.0±1.0 and 2.40±3.12meq KOH/g and unsaponifiable matter 17.20±1.0 and 20.00± 0 respectively. Conclusion:The low oil content of the seeds obtained in this study strongly indicates its prospects for commercial extraction.
